Hi Robert, all, it's obvious that there is a wide range of opinions not only on CMake itself, but also (and in particular) on what it means for Boost to "support CMake". And while I'm happy to see that you are suggesting a "Request for Proposals" rather than a "solution", I still think the problem space is a bit ill-defined. Perhaps we need to talk a bit about requirements first, which proposals need to meet to be eligible. (For example, one requirement I'd insist on would be "the proposal must give project maintainers enough latitude to decide themselves whether to adopt the proposed solution", i.e. any monolithic solution would by design be excluded.) While I'm not a big fan of overly formal processes, I'm afraid that the effort people put into such proposals will just lead to frustration as things will stall again, eventually. And as long as we can't even come to some basic agreement as to how to move forward (not even involving technical aspects of any particular solution), I think it would be irresponsible to invite people to submit proposals. Sorry, Stefan -- ...ich hab' noch einen Koffer in Berlin...
